Check Digit Verification of cas no

The CAS Registry Mumber 18931-19-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,3 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 18931-19:
(7*1)+(6*8)+(5*9)+(4*3)+(3*1)+(2*1)+(1*9)=126
126 % 10 = 6
So 18931-19-6 is a valid CAS Registry Number.

Efficient synthesis of phenalenone derivatives by rhodium(II)-catalyzed reactions

Lee, Yong Rok,Suk, Jung Yup

, p. 4795 - 4799 (2000)

An efficient synthesis of phenalenone derivatives is achieved by rhodium(II)-catalyzed reactions of 2-diazo-1H-1,3-phenalenedione with a variety of substrates in moderate yields. This method also provides a rapid route to biologically interesting polycycles and heterocycles. (C) 2000 Elsevier Science Ltd.
